Phoenix Contact RFC 4072S, User Manual, Page: 59 / 272

Description of the RFC 4072S
108580_en_02 PHOENIX CONTACT
59 / 272
2.11.1 Ethernet connection
Four standardized Ethernet interfaces are available for connecting the Ethernet network.
The LAN1 and LAN2 interfaces are each assigned a separate MAC address. A common
MAC address is assigned to the LAN3.1 and LAN3.2 interfaces that are switched device-
internally.
LAN1 is preconfigured as the PROFINET controller interface. The LAN3.1 and LAN3.2 inter-
faces are preconfigured as the device interface.
The Ethernet network is connected via an RJ45 socket.
For the interface assignment, please refer to “Ethernet interfaces” on page 238 .
Operating the RFC 4072S as a PROFINET device (firmware version: 2019.0 LTS)
If you are operating the RFC as a PROFINET device via the LAN3.1 or LAN3.2 interface,
avoid disconnecting and connecting the Ethernet cable during runtime. Otherwise, the
RFC must be restarted to reestablish the application relationship with the higher-level
PROFINET controller.
More detailed information on the interfaces:
IP address assignment: Section “Configuring the controller IP settings” on page 93 .
Use Ethernet cables according to CAT5 of IEEE 802.3 for operation with up to 100 Mbps.
Please note that for operation with 1000 Mbps (Gigabit), cables with four wire pairs
(twisted pairs, eight wires in total), which at least meet the requirements of CAT5e, must
be used.
When working on PROFINET/PROFIsafe and its components, the following documents
must always be available and observed at all times.
– PROFINET Installation Guideline for Cabling and Assembly
– PROFIsafe System Description
– PROFIBUS Guideline, PROFIsafe Policy
– PROFIsafe – Environmental Requirements Guideline
These documents are available on the Internet at www.profinet.com or you can contact
your local Phoenix Contact representative regarding these documents (see also Section
“Documentation” on page 232 ).
Please also observe the relevant information on PROFINET and PROFIsafe, which is
available on the Internet at www.profisafe.net .
